我们有一个使用Bouncy Castle的应用程序使用PBEWITHSHA256AND128BITAES-CBC-BC算法加密数据.它在运行OpenJDK 1.7的Ubuntu上运行良好.但是当我们将它移动到也运行OpenJDK 1.7的RedHat 6.4时,我们得到以下异常：
java.security.NoSuchAlgorithmException
关于可能导致这种情况的任何想法.我们如何在RedHat 6.4中添加PBEWITHSHA256AND128BITAES-CBC-BC算法？
附：该应用程序在JBoss中运行.
private String cryptoAlgorithm = "PBEWITHSHA256AND128BITAES-CBC-BC";
Security.addProvider(new BouncyCastleProvider());
// load passPhrase from configured external file to char array.
char[] passPhrase = null;
try {
passPhrase = loadPassPhrase(passPhraseFile);
} catch (FileNotFoundException e) {
throw BeanHelper.logException(LOG,methodName,new EJBException("The file not found: " + passPhraseFile,e));
} catch (IOException e) {
throw BeanHelper.logException(LOG,new EJBException("Error in reading file: " + passPhraseFile,e));
}
PBEKeySpec pbeKeySpec = new PBEKeySpec(passPhrase);
try {
SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance(cryptoAlgorithm);
SecretKey newSecretKey = secretKeyFactory.generateSecret(pbeKeySpec);
return newSecretKey;
} catch (NoSuchAlgorithmException e) {
throw BeanHelper.logException(LOG,new EJBException("The algorithm is not found: " + cryptoAlgorithm,e));
} catch (InvalidKeySpecException e) {
throw BeanHelper.logException(LOG,new EJBException("The key spec is invalid",e));
}

解决方法
你的类路径中是否有BouncyCastle提供程序JAR(例如bcprov-jdk15on-149.jar)？
我使用最小的CentOS 6.4(64位)安装,OpenJDK 1.7和BouncyCastle 1.49测试了您的场景,并发现它没有任何问题.
我将JAR放在JRE lib / ext目录中：
/usr/lib/jvm/java-1.7.0-openjdk.x86_64/jre/lib/ext
